Peach tree named ‘NJ360’

ABSTRACT

A new and distinct peach variety of Prunus persica named ‘NJ360’ is provided. This variety is distinguished from other peach varieties by its unique combination of showy flowers, medium to large, round, semi-freestone fruit, with a red to greyed-purple blush over a bright yellow-white ground, ripening in mid-season, and possessing aromatic, sweet, sub-acid flavor.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

This invention was made with government support under, contract or grantMultistate Research Project NE-9, entitled Conservation and Utilizationof Plant Genetic Resources, awarded or sponsored by the NationalInstitute of Food and Agriculture. The government has certain rights inthe invention.

Latin name of genus and species of the plant claimed: Prunus persica L.

Variety denomination: ‘NJ360’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of peachtree named ‘NJ360’ that resulted from crossing a peach seedlingselection ‘H24-128-01224’ (non-patented) as the seed parent with ‘NJ354’(U.S. Plant Pat. No. 23,669). The new variety differs from seed parent‘H24-128-01224’ in that the new variety produces white fleshed fruitthat ripen 3 days earlier and have different, more preferable values offlavor and aromatics. The new variety differs from pollen parent ‘NJ354’in that the new variety ripens about 2 weeks later and more consistentlyproduces fruit with different, more preferable values of sweetness andflavor. The resulting tree was selected when growing in a cultivatedarea as the 135^(th) tree in the 14^(th) row of Block H at a fruitresearch farm in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

‘NJ360’ differs from the related cultivar ‘White Lady’ (U.S. Plant Pat.No. 5,821), in that trees of ‘NJ360’ crop more consistently are lesssusceptible bacterial leaf spot (Xanthomonas campestris pv. pruni) than‘White Lady’. The ‘NJ360’ variety is also distinguished from other peachvarieties due to the following unique combination of characteristics:

Produces medium to large, nearly round, semi-freestone fruit with a lowtendency to split when adequately cropped.

Fruits have an attractive red to greyed-purple blush over a brightyellow-white ground color.

Excellent production of fruit that ripen in mid-season on trees with lowsusceptibility to bacterial leaf spot.

Fruit have superior eating quality due to their aromatic, sweet, andsub-acid flavor.

The variety was asexually reproduced at a fruit research farm in CreamRidge, N.J. Asexual reproduction of this new variety by buddingonto >Lovell=peach seedling rootstock (non-patented) shows that theforegoing characteristics are so reproduced.

The following detailed description concerns the original tree, ‘NJ360’.The original tree and asexual progeny have been observed growing in acultivated area at a fruit research farm in Cream Ridge, N.J. Certaincharacteristics of this variety, such as growth and color, may changewith changing environmental conditions (such as, light, temperature,moisture, nutrient availability) or other factors. Color descriptionsand other terminology are used in accordance with their ordinarydictionary descriptions unless the context clearly indicates otherwise.Color designations are made with reference to The Royal HorticulturalSociety (R.H.S.) Colour Chart (1966 Ed.)

BRIEF DESCRIPTION OF THE DRAWINGS

This new variety is illustrated by the accompanying photographicdrawings of the ‘NJ360’ plant at approximately seven (7) years old,depicting the peach tree by the best possible color representation usingcolor photography. Colors are approximate as color depends onhorticultural practices, such as light level, fertilization rate, andother conditions and, therefore, the color characteristics of this newvariety should be determined with reference to the observationsdescribed herein, rather than from these illustrations alone.

FIG. 2 is a color photograph taken on Jul. 29, 2019 of characteristicmature fruit and stones of ‘NJ360’. Whole fruit are presented in twopositions and both a transverse and longitudinal cross section toillustrate that the pericarp partially adheres to the pit when the fruitis mature. The stones exemplify the obovate shape and pits and grooveson the surface of the stone.

The colors of and illustration of this type may vary with lighting andother conditions under which conditions and, therefore, colorcharacteristics of this new variety should be determined with referenceto the observations described herein, rather than from theseillustrations alone.
